 extracting, from the first data packet, a plurality of samples associated with a plurality of signals; and 
 generating, based on the extracted samples, a plurality of data streams corresponding to the plurality of signals. 
 
     
     
       9. The method of  claim 8 , wherein generating comprises de-bundling the plurality of samples into the plurality of data streams according to a predetermined pattern. 
     
     
       10. The method of  claim 9 , further comprising receiving an indication of the predetermined pattern from the first wireless device. 
     
     
       11. The method of  claim 8  wherein:
 the predetermined pattern comprises N≥2 samples, from each data stream, that are identified by respective sampling identifiers (sIDs) k+stepover*m, 
 m is a sequence of integers from 0 to N−1, 
 stepover is an integer value of greater than or equal to 2, and 
 k is an sID of a first sample to be de-bundled from the first data packet. 
 
     
     
       12. A first wireless device configured to transmit a plurality of samples to a second wireless device using machine-to-machine communication, the first wireless device comprising processing circuitry configured to:
 receive a plurality of data streams, wherein the plurality of data streams comprise samples of a corresponding plurality of signals; 
 generate a first data packet based on bundling at least one sample from each of the plurality of received data streams into the first data packet according to a predetermined pattern, wherein:
 the predetermined pattern comprises N≥2 samples, from each received data stream, that are identified by respective sampling identifiers (sIDs) k+stepover*m, 
 m is a sequence of integers from 0 to N−1, 
 stepover is an integer value of greater than or equal to 2, and
